DWI
What does normal signal in the diffusion-weighted images mean?

Would a large brain tumor show normal signal in diffusion-weighted images?

Thanks

 DWI reflects the degree of water molecule movement. If the degree of water molecule movement in the tumor is the same as the normal tissue, the signal of DWI will have no difference between the tumor and the normal tissue.
